One thing you need to do is open every window and door when you get there, and maybe even use a fan to blow it out. The more you can air it, the better it will be. If you need to, try using a dehumidifyer; as cabins in the woods tend to stay damp, so you get musty odors, too. Febreeze every non-wood surface that you can, as anything upholstered will hold the odor. So will throw rugs, etc. When you are there (and can keep an eye on them), burn some candles, they can be unscented or scented. They will help dry things out, too.

My choice would be vinegar as it will kill mold spores not just cover the scent. We used to fire up the wood stove to dry the cabin out. They all smell must after being closed up, even my house after only a long weekend.
